Title: Detergent compositions and processes for making them
IPC: C11D3/06
Filed: 1952-06-27
Abstract: Spray-dried compositions containing an organic detergent and a phosphate are agitated in the presence of sufficient free moisture to hydrate the phosphate.  The tendency of the products to cake is thus reduced.  The process may comprise agitating the spray-dried particles while treating them with a fine spray of water, but if the spray-dried product still contains sufficient water to hydrate the phosphate it may be sufficient to agitate the product until the phosphate is hydrated, no additional water being supplied. The detergents may be soaps or synthetic detergents, which may be anionic, cationic or non-ionic.  Specified anionic synthetic detergents are sulphated or sulphonated compounds having an alkyl group of 8-26 carbon atoms, such as (1) sulphuric esters of polyhydric alcohols partly esterified with higher fatty acids, e.g. coconut oil monoglyceride monosulphate and tallow diglyceride monosulphate, (2) higher alkyl sulphates, e.g. lauryl sulphate, cetyl sulphate and the sulphates of alcohols derived from coconut oil, (3) higher fatty-acid esters of lower alkylol sulphonic acids, e.g. the oleic ester of isethionic acid and similar esters of 2, 3-dihydroxypropane sulphonic acid, (4) sulphated higher fatty acid alkylolamides, e.g. ethanolamides, (5) higher fatty acid amides of aminoalkyl sulphonic acids, e.g. lauric acid tauride, (6) sulphonated alkylaryl compounds, e.g. sulphonation products of higher alkylated derivatives of benzene, toluene, xylenes, naphthalene, phenanthrene or anthracene or of higher alkylated phenols, cresols and phenol ethers; the anionic detergents may be used as alkali or alkaline-earth metal, ammonium, amine or alkylolamine salts. Specified cationic detergents are (1) salts of alkyl-substituted heterocyclic tertiary amines, e.g. salts of glyoxalidines substituted in the 2-position with a higher alkyl group and optionally substituted in the i-position with a lower alkyl or alkylol group, and (2) salts of polyoxyethylene substitution products of fatty amines. Specified non-ionic detergents are (1) reaction products of ethylene oxide with carboxylic acids or their anhydrides, alcohols, and amides of high molecular weight, (2) alkyl ethers, alkyl thioethers, sterol ethers and alkylphenol ethers and fatty-acid esters of polyethylene glycol, polypropylene glycol, polybutylene glycol and polyglycerol, and (3) polyalkylene glycol ethers of partly esterified glycol, glycerol, sorbitol and mannitol and anhydro derivatives thereof, Specified phosphates are sodium tripolyphosphate, tetrasodium, pyrophosphate and trisodium orthophosphate or mixtures thereof.  The compositions may contain additional ingredients, e.g. water-soluble sulphates, silicates, borates or carbonates, carboxymethyl cellulose, higher aliphatic alcohols, mono-esters of polyhydric alcohols, aliphatic carboxylic acid amides or alkylolamides, disinfectants such as mercury compounds or phenols, fluorescent dyes and perfumes.  Examples of suitable compositions are given.  Specification 591,211 is referred to.

Title: Improvements in or relating to the production of pyrazine derivatives
IPC: C07D241/28
Filed: 1944-08-30
Abstract: 2-Amino-3-carboxypyrazine compounds are manufactured by treating lumazine, an alkyl- or phenyl-substituted lumazine or phenanthralumazine with an alkali metal hydroxide in aqueous solution, in quantity such as to form exclusively or preponderantly an alkali metal salt of a corresponding 2-amino-3-carboxypyrazine, and isolating this salt or the free 2-amino-3-carboxypyrazine compound from the reaction mixture.  The reaction may be carried out at atmospheric or increased pressure, and the free acid may be recovered from the reaction mixture by direct acidification or by way of the barium salt.  In examples: (1) hydrated lumazine is heated to 170 DEG  C. in a steel bomb with 2.25 molecular proportions of aqueous sodium hydroxide and the reaction mixture is acidified to pH 2.5 with hydrochloric acid to liberate 2-amino-3-carboxypyrazine; (2) crude 7-methyl-lumazine is refluxed with aqueous sodium hydroxide, the product is neutralized with hydrochloric acid and ammonia is added followed by barium chloride to precipitate the barium salt of 2-amino-3-carboxy-6-methylpyrazine, from which the free acid is obtained by boiling with hydrochloric acid; (3) crude 6 : 7 - dimethyl - lumazine similarly yields 2-amino - 3 - carboxy - 5 : 6 - dimethylpyrazine; (4) crude 6 : 7-diphenyl-lumazine similarly gives 2-amino-3-carboxy-5 : 6-diphenylpyrazine; (5) phenanthralumazine is heated to 225-235 DEG  C. in a steel bomb with 5.35 molecular proportions of aqueous sodium hydroxide, and the product is acidified with hydrochloric acid to liberate 2 - amino - 3 - carboxyphenanthrapyrazine; (6) anhydrous 7-methyl-lumazine is heated to 170-5 DEG  C. in a steel bomb with 4.8 molecular proportions of aqueous sodium hydroxide and the product is treated as in (1) to liberate the product of (2); (7) 6 : 7-dimethyl-lumazine similarly yields the product of (3).  The sodium hydroxide may be replaced by potassium hydroxide.  The Specification as open to inspection under Sect. 91 comprises also the subject-matter of Specification 599,688, and an additional example in which 2-amino-3-carboxypyrazine is heated to 170 DEG  C. in a steel bomb with aqueous sodium hydroxide and the product is acidified with hydrochloric acid to liberate 2-hydroxy-3-carboxypyrazine.  This subject-matter does not appear in the Specification as accepted.
Patent GB-889512-A (GB)
Title: Improvements in or relating to peak-reading digital voltmeters
IPC: H03M1/00
Filed: 1959-05-14
Abstract: 889,512. Analogue-to-digital converters. CONSOLIDATED ELECTRODYNAMICS CORPORATION. May 14, 1959 [May 19, 1958], No. 16515/59. Class 40 (1). [Also in Group XXXVI] In a digital voltmeter for indicating the peak amplitude of an input signal e.g. from a mass spectrometer, a counter 10 is advanced until the analogue voltage derived from its output at 12 exceeds the instantaneous level of the input signal. Counter 10 is advanced by multivibrator 32 and the analogue voltage from converter 12 is compared with the input signal in summing network 24, 25. A trigger circuit 30 changes from its normal state when the output of network 24, 25 is zero and gates multivibrator 32 so that the count is interrupted. If the input signal level is higher than that corresponding to the maximum count of counter 10, a carry pulse is generated by that counter when the maximum count is reached, this pulse being passed by OR gate 34 to operate monostable multivibrator 36 and advances ring counter 38 by one position. Counter 38 operates, according to its position, one of contacts 16, 18, 20, 22 of a number of high-speed relays, the switches respectively introducing attenuation of the input signal in the ratio of 3, 10, 30, 100:1. Counter 38 also resets counter 10 by way of gating circuit 40 to a position corresponding to the maximum count and the attenuation ratio e.g. to a count of 333 when the attenuation ratio is 3: 1 and the maximum count is 999, so that the counter does not have to start from zero each time a new attenuation ratio is selected. The outputs of counters 10, 38 indicate the peak input signal level when balance is reached in network 24, 25. To further reduce the delay inherent in the voltmeter, a trigger circuit 44 is provided, which charges its state when the input signal level exceeds that corresponding to the maximum count of 3: 1 or more, trigger 44 controlling the setting of attenuator 14 by way of gate 34, multivibrator 36 and counter 38 so that the next attenuation step is selected without having to wait for counter 10 to reach its maximum count. A new peak measurement may be made after applying an external resetting pulse to counters 10, 38.

Filed: 1922-06-15
Abstract: 199,250. Anglo-Persian Oil Co., Ltd., and Taylor, J. June 15, 1922. Leakage-preventing devices.-To prevent leakage from centrifugal pumps, more particularly pumps used for light oils, a clearance space i opening into the suction chamber is provided between the impeller and the bearing. The parts are constructed so that this space i is on a plane closer to the plane of the delivery outlets of the impeller than the clearance space a between the impeller and the pump casing. The hub m of the impeller has an annular extension l which projects into a recess in the end of the gland o. This gland is mounted in a coned seating p in the casing d and is firmly held by means of the nut s. Metallic packing rings u are arranged between the gland and the impeller shaft and are separated from each other by rings w of leather or like material: the pressure upon the rings may be adjusted by means of the nut z. By these means the liquid tending to escape between the impeller and the bearing is forced to flow in the direction imposed by the suction of the impeller.
